.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...

Light onshore flow and low seas will prevail through today into
tomorrow, with winds then turning more NE by early Wed. Offshore
flow then continues through the later half of the week as a cold
front moves through the area and reinforces this flow. As this
front moves into the area, the pressure gradient overhead will
tighten and winds/seas will pick up in response. Expected somewhat
elevated conditions by late Wed into the early weekend, with SCA
conditions likely as early as Thursday sunrise.
